RESUMO

BACKGROUND: Self-medication (SM) is a rising public health issue, especially in developing countries. It can be associated with various problems such as the delayed seeking of medical advice, drug interactions, and serious events such as antimicrobial drug resistance. We aimed to evaluate the Egyptian general population's knowledge, attitudes, and practices of SM. METHODS: We employed a cross-sectional design between February 7th and March 8th, 2023 using a self-administered questionnaire available in Arabic. The questionnaire was developed based on previous studies and included four domains: sociodemographic data, knowledge, attitude, and practice of SM. We utilized both online (Google Forms) and paper surveys, utilizing convenience and snowball sampling methods. Data were analyzed using R Statistical Software (v4.1.3; R Core Team 2022). RESULTS: 1630 Egyptian individuals (838 females and 792 males) from the seven provinces were enrolled, with a median age of 25 years (IQR: 22-40). Around 55.97% and 48.28% of the participants had good knowledge and favorable attitudes regarding SM respectively, while 62.8% had practiced SM in the previous three months. The most frequently used medications were painkillers (60.74%) followed by antibiotics (32.13%) and antipyretics (28.61%). The pharmacist's recommendation was the source of SM for 53.61% while 31.53% used old medications at home. Most participants (59.08%) practiced SM because they thought they had simple or minor symptoms. The multivariate regression analysis revealed that females had significantly higher knowledge of SM than males (aOR: 2.10; 95%CI: 1.64-2.71; p-value < 0.001), with no significant differences in practice (aOR: 1.24; 95%CI: 0.99 - 1.56; p-value = 0.065). Individuals working or studying in the medical field were significantly more knowledgeable about SM (aOR: 4.30; 95%CI: 3.27-5.69; p-value < 0.001) and more likely to practice SM (aOR: 1.65; 95%CI: 1.26-2.17; p-value < 0.001). The odds of SM decreased with favorable attitudes (aOR: 0.44; 95%CI: 0.36-0.55; p-value < 0.001) while surprisingly, knowledge level was not significantly contributing to SM practice (aOR: 1.15; 95%CI: 0.90-1.48; p-value = 0.268). CONCLUSIONS: SM is prevalent in Egypt, highlighting the importance of raising awareness and encouraging physician consultation as a priority. Governments, healthcare organizations, and educational institutions need to collaborate to provide the necessary support and resources.

RESUMO

PURPOSE: We investigated the efficacy and safety of fluoxetine, a selective serotonin reuptake inhibitor, for treating refractory primary monosymptomatic nocturnal enuresis in children. MATERIALS AND METHODS: Children 8-18 years old with severe primary monosymptomatic nocturnal enuresis unresponsive to alarm therapy, desmopressin, and anticholinergics were screened for eligibility. After excluding children with daytime urinary symptoms, constipation, underlying urological, neuropsychiatric, endocrinological, or cardiac conditions, patients were randomly and equally assigned to 10 mg fluoxetine once daily or placebo for 12 weeks. The primary outcome was treatment response according to the International Children's Continence Society terminology. Treatment-related adverse effects and nighttime arousal were secondary outcomes. RESULTS: A total of 150 children were enrolled, of whom 110 (56 in fluoxetine group and 54 in placebo group) with a mean age of 11.8 (SD 2.46) years were finally analyzed. After 4 weeks, 7.1% and 66.1% of the fluoxetine group achieved complete response and partial response (defined as 50%-99% reduction of the number of wet nights), respectively, versus 0% and 16.7% of the placebo group (P < .001). At 12 weeks, complete and partial responses were achieved in 10.7% and 21.4% of the fluoxetine group, respectively (vs 0% and 14.8% of the placebo group, P = .023). Fluoxetine-treated patients had fewer wet nights (4.7 [SD 4.2] fortnightly vs 9.7 [SD 3.5] at 4 weeks, P < .001; 5.7 [SD 4.4] vs 9.9 [SD 3.4] at 8 weeks, P < .001; 7.5 [SD 4.6] vs 9.9 [SD 3.4] at 12 weeks, P = .003). Fluoxetine was associated with improved nighttime arousal (P = .017), and minor and rapidly reversible adverse effects in 5 (8.9%) patients. CONCLUSIONS: Fluoxetine is safe treatment for refractory primary monosymptomatic nocturnal enuresis in children with good initial response that declines at 12 weeks.

RESUMO

OBJECTIVE: Minimal invasive extracorporeal circuits (MiECC) have been associated with a significant reduction in the incidence of postoperative atrial fibrillation (AF). Nevertheless, AF remains one of the most common complications following elective primary coronary artery bypass grafting (CABG). The aim of this study was to identify the predictors of AF persisting beyond the hospital stay in elective primary CABG patients. METHODS: We conducted a retrospective analysis for the predictors of AF that persisted beyond discharge between all patients who received an elective isolated CABG in our institution between 2009 and 2014. Patients with a positive history for intermittent or persistent AF were excluded from the analysis. Almost all patients were discharged to a rehabilitation facility where they stayed for 3 to 4 weeks postoperatively. At rehab approximately 91% of them received Holter monitoring at least once prior to their discharge. RESULTS: A total of 770 patients were included in the analysis of which 763 patients survived the in-hospital stay. The incidence of AF at hospital discharge was 4.2% (32/763) while that on Holter monitor at Rehab was 1.5% (10/685). Age and the type of extracorporeal circuit (ECC) utilized were the only significant predictors for both AF at discharge (p < 0.01 both) and on Holter monitor in rehab (p < 0.01 and 0.02, respectively). This was also confirmed on multivariate analysis. CONCLUSION: Our findings show that the benefits of MiECC regarding the incidence of postoperative AF persist beyond hospital discharge. They may thus positively influence the outcomes of patients beyond the early postoperative period.

RESUMO

OBJECTIVE: To assess the effect of bladder neck morphology and its incision (BNI) in patients with posterior urethral valve (PUV) on early reintervention rate. PATIENTS AND METHODS: Infants undergoing PUV ablation (PVA) before 24 months of age and had at least 18 months of follow-up, were categorized into three groups according to the bladder neck appearance on baseline radiological and endoscopic examination: group 1; normal bladder neck underwent PVA, group 2; high bladder neck underwent PVA plus BNI, group 3; high bladder neck underwent PVA only. Early reintervention was defined as the need for check cystoscopy because of persistent renal function deterioration, worsening hydronephrosis and/or unsatisfactory VCUG improvement during the 1st six months post primary PVA. RESULTS: Between 2000 and 2017, a total of 114 patients underwent PVA and met the study criteria with a median follow-up of 58 (18-230) months. For group 1, 16 (22.9%) patients needed readmission. Check cystoscopy was free and no further intervention was performed in 5(7.5%) and re-ablation was performed in 11(15.7%) patients. For group 2, 3(14.3%) patients needed reintervention. Re-ablation and re-ablation plus BNI were performed in 1(4.8%) and 2(9.5%), respectively. For group 3, cystoscopy was free in 1(4.3%), re-ablation and re-ablation plus BNI were performed 2(8.7%) and 1(4.3%), respectively. There were no significant differences in the re-admission and re-intervention rates among the three study groups (p=0.65 and p=0.50, respectively). CONCLUSION: In morphologically high bladder neck associated PUV, concomitant BNI with PVA doesn't reduce early re-intervention rate.

RESUMO

PURPOSE: We studied the effect of oxybutynin on bladder and upper urinary tract outcomes in infants following posterior urethral valve ablation. MATERIALS AND METHODS: Patients younger than 12 months old who had undergone primary endoscopic valve ablation for posterior urethral valves were screened for eligibility. Patients who had undergone urinary diversion or had other conditions that could affect lower urinary tract function were excluded. Study patients were randomized to either oxybutynin (0.2 mg/kg 3 times daily) until toilet training or active observation. The study end points were serum creatinine, estimated glomerular filtration rate, hydronephrosis improvement, vesicoureteral reflux resolution, febrile urinary tract infection and toilet training. RESULTS: A total of 49 infants (24 receiving oxybutynin and 25 undergoing observation) were enrolled between December 2013 and September 2015 and completed at least 1 year of followup. Oxybutynin was discontinued before toilet training in 5 patients due to facial flushing in 2, bladder and upper tract dilatation in 2, and cognitive changes in 1. After a median followup of 44.2 months (range 12 to 57.6) median serum creatinine and estimated glomerular filtration rate were not significantly different between the groups (p=0.823 and p=0.722, respectively). Renal units in the oxybutynin group had a greater likelihood of hydronephrosis improvement (61.9% vs 34.8%, p=0.011) and resolution of vesicoureteral reflux (62.5% vs 25%, p=0.023). Febrile urinary tract infection (29.2% vs 40%, p=0.404), completion of toilet training (70.8% vs 76%, p=0.748) and age at toilet training (p=0.247) did not differ significantly between the oxybutynin and observation groups. CONCLUSIONS: Oxybutynin enhances hydronephrosis improvement and vesicoureteral reflux resolution following primary endoscopic valve ablation in infants but periodic monitoring is warranted.

RESUMO

BACKGROUND: The study aims at evaluating the time-course changes of pre-corneal tear film after simultaneous phacoemulsification and limbal relaxing incisions (LRIs) performed in 2 groups of patients; group-A had vertical and group-B had horizontal LRIs. METHODS: Fourty-two eyes of 28 patients with co-existing cataract and corneal astigmatism were studied before and after simultaneous cataract surgery and LRIs (at weeks 1, 4 and 12), patients were classified into 2 groups according to the orientation of LRIs; vertical (A) and horizontal (B) groups. Pre-corneal tear film stability was assessed by measuring the tear break-up time (TBUT) and the tear volume was determined using Schirmer's I test (Basic Schirmer's test; BST), both preoperatively and postoperatively. RESULTS: TBUT was significantly reduced in both the study groups (P = 0.001) without significant reduction regarding basic Schirmer's test values except for the first postoperative week in the horizontal LRI group-B (P = 0.04). CONCLUSIONS: Precorneal tear film stability is altered in the early postoperative period after simultaneous cataract and LRI incisions shown by TBUT measurement values. These changes do not appear to differ significantly depending on the orientation of LRI incisions.

RESUMO

The coronavirus disease 2019 (COVID-19) has rapidly spread across the world since first being identified in Wuhan, China, in late 2019. In order to prepare for the surge of patients and the corresponding increase in radiology exams, clear and detailed policies need to be implemented by hospitals and radiology departments. In this article, we highlight the experiences and policies at LAC+USC Medical Center, the largest single provider of healthcare in LA County. Our policies aim to reduce the risk of transmission, guide patient management and workflow, preserve and effectively allocate resources, and be responsive to changing dynamics. We hope this communication may help other institutions in dealing with this pandemic as well as future outbreaks.

RESUMO

Human kidney function is underpinned by approximately 1,000,000 nephrons, although the number varies substantially, and low nephron number is linked to disease. Human kidney development initiates around 4 weeks of gestation and ends around 34-37 weeks of gestation. Over this period, a reiterative inductive process establishes the nephron complement. Studies have provided insightful anatomic descriptions of human kidney development, but the limited histologic views are not readily accessible to a broad audience. In this first paper in a series providing comprehensive insight into human kidney formation, we examined human kidney development in 135 anonymously donated human kidney specimens. We documented kidney development at a macroscopic and cellular level through histologic analysis, RNA in situ hybridization, immunofluorescence studies, and transcriptional profiling, contrasting human development (4-23 weeks) with mouse development at selected stages (embryonic day 15.5 and postnatal day 2). The high-resolution histologic interactive atlas of human kidney organogenesis generated can be viewed at the GUDMAP database (www.gudmap.org) together with three-dimensional reconstructions of key components of the data herein. At the anatomic level, human and mouse kidney development differ in timing, scale, and global features such as lobe formation and progenitor niche organization. The data also highlight differences in molecular and cellular features, including the expression and cellular distribution of anchor gene markers used to identify key cell types in mouse kidney studies. These data will facilitate and inform in vitro efforts to generate human kidney structures and comparative functional analyses across mammalian species.

RESUMO

OBJECTIVE: To evaluate differences in pathological features and prognostics across four bladder cancer histopathological types: urothelial carcinoma (UC), urothelial carcinoma with variant histology (UCV), squamous cell carcinoma (SCC) and adenocarcinoma (ADC), utilizing a large cohort of radical cystectomy (RC) patients. METHODS: A retrospective analysis of patients who underwent RC at a single institution in Egypt between 1997 and 2004 was performed. Kaplan-Meier and multivariable analyses were performed to evaluate the prognostic significance of pathological features including tumor stage, grade, lymphovascular invasion (LVI), and lymph node (LN) involvement in the different subtypes on disease-free survival (DFS). RESULTS: 1238 patients (975 male, 263 female) were included, of whom 577 (47%) had UC, 174 (14%) UCV, 398 (32%) SCC, and 89 (7%) ADC. Median age was 54 (20-87) years and median follow-up was 40 months (0-110). There were significant differences in stage, grade, LVI, LN involvement, and presence of schistosomiasis across the subtypes (all p < 0.05). The prognostic significance of LVI was more evident in SCC (HR 2.14, p = 0.003) and ADC (HR 2.17, p = 0.044) than in UC (HR 1.66, p = 0.008). LN involvement was the strongest prognostic factor in UCV (HR 2.14, p = 0.012). CONCLUSIONS: There are significant differences in clinicopathological features and their prognostic impact across bladder cancer subtypes. The prognostic significance of LVI is more evident in SCC and ADC, while LN involvement is more prognostic in UCV. Determining independent predictors in individual subtypes can guide multimodal treatment selection and clinical trial design.

RESUMO

PURPOSE: We sought to evaluate long-term outcomes of the Bricker conduit urinary diversion in children. MATERIALS AND METHODS: We retrospectively reviewed the database of a single tertiary center for children who had undergone ileal conduit between 1981 and 2011. Patients followed for less than 1 year were excluded. Patient files were reviewed for demographics, diversion indication, preoperative imaging, surgical details, hospital readmissions and followup data. Renal function at baseline and last followup was assessed by estimated glomerular filtration rate, calculated using the modified Schwartz or MDRD (Modified Diet in Renal Disease) formula. Growth charts elucidated patient growth patterns, while an internally designed quality of life questionnaire demonstrated patient and family satisfaction with the procedure. RESULTS: We evaluated 29 children who underwent Bricker conduit at a median age of 10 years (range 2 to 18) and were followed for a median of 91 months (16 to 389). Neuropathic bladder was the underlying diagnosis in 72.4% of cases. Hydronephrosis improved or remained stable in 39 of 55 studied renal units (70.9%). Although no statistically significant difference was observed between mean ± SD baseline (64.5 ± 46 ml/minute/1.73 m(2)) and last followup estimated glomerular filtration rate (54.1 ± 44.9 ml/minute/1.73 m(2)), chronic kidney disease stage had worsened in 13 patients (44.8%), end-stage kidney disease had developed in 11 patients and 9 patients had died. Six patients underwent undiversion after stabilization of renal function. Linear growth was negatively affected in 12 patients (41.4%), and 85% reported poor quality of life. A total of 19 hospital readmissions were required in 14 patients to treat diversion related complications. CONCLUSIONS: The Bricker conduit does not seem to halt renal deterioration in children. Negative impact on growth and quality of life, and the anticipated rate of complications are significant limitations of the procedure in the pediatric population.

RESUMO

BACKGROUND: Four-dimensional computed tomography (4D CT) has emerged as an extremely sensitive preoperative imaging modality for primary hyperparathyroidism compared with the historical use of sestamibi and ultrasound (US). Specialized volume rendering and technical modifications further enhance this technique for operative guidance while reducing radiation exposure. METHODS: Patients undergoing parathyroidectomy for primary hyperparathyroidism from December 2010 to September 2013, carried out by two surgeons at a tertiary cancer center, were evaluated. Comparison was made between the three imaging modalities (4D CT, sestamibi, and US) for preoperative localization rate and accuracy. Biochemical parameters and radiation exposure were also analyzed. RESULTS: A total of 202 patients were identified from the database and 200 patients were included in the analysis. All patients underwent 4D CT (100 %), 185 sestamibi (92.5 %) and 186 US (93 %). In patients with single-gland disease (n = 153), 4D CT, sestamibi, and US were positive in 96 %, 65.4 % and 57.7 % of patients, respectively and, when positive, were accurately localized in 97.2 %, 93.4 % and 96.3 % of patients, respectively. In patients with multigland disease (MGD) [n = 47], 4D CT, sestamibi, and US predicted MGD in 32 %, 0 %, and 13.6 % of patients, respectively. With our technique modification, radiation exposure from 4D CT approached that of sestamibi. CONCLUSIONS: Low-dose, modified 4D CT with volume rendering when compared with sestamibi has a statistically significant higher positivity rate, improved accuracy rate, provides excellent images, superior surgical planning, and has a comparable radiation exposure risk profile. Consideration should be made for the abandonment of routine sestamibi single-positron emission computed tomography (SPECT), with 4D CT as the preoperative imaging modality of choice.

RESUMO

PURPOSE: Staging of childhood renal tumors is crucial for treatment planning and outcome prediction. We sought to identify whether computerized tomography could accurately predict the local stage of childhood renal tumors. MATERIALS AND METHODS: We retrospectively reviewed our database for patients diagnosed with childhood renal tumors and treated surgically between 1990 and 2013. Inability to retrieve preoperative computerized tomography, intraoperative tumor spillage and nonWilms childhood renal tumors were exclusion criteria. Local computerized tomography stage was assigned by a single experienced pediatric radiologist blinded to the pathological stage, using a consensus similar to the Children's Oncology Group Wilms tumor staging system. Tumors were stratified into up-front surgery and preoperative chemotherapy groups. The radiological stage of each tumor was compared to the pathological stage. RESULTS: A total of 189 tumors in 179 patients met inclusion criteria. Computerized tomography staging matched pathological staging in 68% of up-front surgery (70 of 103), 31.8% of pre-chemotherapy (21 of 66) and 48.8% of post-chemotherapy scans (42 of 86). Computerized tomography over staged 21.4%, 65.2% and 46.5% of tumors in the up-front surgery, pre-chemotherapy and post-chemotherapy scans, respectively, and under staged 10.7%, 3% and 4.7%. Computerized tomography staging was more accurate in tumors managed by up-front surgery (p <0.001) and those without extracapsular extension (p <0.001). CONCLUSIONS: The validity of computerized tomography staging of childhood renal tumors remains doubtful. This staging is more accurate for tumors treated with up-front surgery and those without extracapsular extension. Preoperative computerized tomography can help to exclude capsular breach. Treatment strategy should be based on surgical and pathological staging to avoid the hazards of inaccurate staging.

RESUMO

We report the fabrication of carbon nanotube (CNT) based gas sensors functionalized with different metallic nanoparticles (NPs) (Au, Pd, Ag) with exceptionally high responses towards four test gases (NH3, CO2, CO and ethanol). The CNT networks were fabricated through a low cost spray deposition process while the NPs were deposited by a thermal evaporation process. CNT based gas sensors functionalized with Au with a nominal thickness of 1.0 nm showed superior response towards NH3, CO and ethanol. The sensors' normalized responses reached 92%, 22% and 32% with concentrations of 100 ppm, 50 ppm and 100 ppm for NH3, CO and ethanol respectively. CNT based gas sensors functionalized with Pd with a nominal thickness of 1.5 nm showed the best performance with CO2. The normalized response reached 3%, 6%, 12% and 17% with concentrations of 500 ppm, 1000 ppm, 2500 ppm and 5000 ppm of CO2 respectively. We also investigated the morphological and optical changes that occur to the NPs upon thermal treatment. Functionalization of CNT films deposited on glass with Au and Ag showed surface plasmon resonance effects that are dependent on the nominal thickness of the functionalization layer.

RESUMO

Recently, the integrated different interdisciplinary studies derived the environmental solutions of the climate change impacts (e.g., cultivation, wastewater treatment, and managing groundwater resources) (Mesalhy et al. 2020, and Gobashy et al. 2021). Thus, this paper focused on the application of bioremediation to maximize the use of wastewater for new reclamation areas in the Northwest Egyptian desert (New Egyptian Delta (NED). In the NED project, the drainage water samples collected from Nile Delta drains will provide the main unconventional water resources for irrigation through the new Hammam canal. Therefore, three Pleurotus strains were grown moderately on two natural media, the first containing Salvia L. (sage) extract (MDA) and the second containing Thymus vulgaris L. (origanum thymus Kuntze, Thymus collinus Salisb) (TDA) extract replacing potato infusions in standard PDA. Pleurotus ostreatus (Jacquin; Kummer) strain records the highest growth among the three tested fungi on modified media. PO records 4.49 and 4.41 cm on (MDA) and (TDA), respectively. There is a marked decrease in the majority of heavy metal concentrations on sterile drainage water amended with PD broth and inoculated with three tested Pleurotus strains individually. At the end of the incubation period, Pleurotus ostereatus which expressed in abbreviation (PO) are more efficient in the removal of Al, Co, Cr, and Ni by 53.15, 95.87, 58.47, and 85.07%; respectively. Pleurorotus pulmonarius (Fr.) which symbolized (PP) is more potent in the removal of Cd, Si, Sn, Sr, and V by 70.37, 56.59, 41.19, 52.78, and 96.24%; respectively. Pleurotus floridanus (NZOR) which indicated as (PF) is actively over the former species in the removal of Ba, Fe, and Mo by 87.84, 46.67, and 97.34%; respectively. Cu, Mn, Pb, As, and Se could not be detected as the control sample recorded measurements below 0.009 mg L-1. An unexpected increase in Zn among the different treatments was detected from 05.04 to 07.01%.

RESUMO

BACKGROUND: The aim of this study is to investigate the impact of the intradermal injection of purified protein derivative (PPD) and PPD skin test reactions on the oncological outcomes of patients with non-muscle invasive bladder cancer (NMIBC) treated by trans-urethral resection of bladder tumor (TURBT) and adjuvant intravesical BCG. METHODS: The study included 100 consecutive patients with NMIBC prospectively given intradermal PPD 1-2 weeks before starting BCG therapy. Another 100 patients with NMIBC not given intradermal PPD before starting BCG were chosen as a historical control. The control group was chosen to be matching with the study group regarding baseline characteristics. The study group was divided into 2 subgroups with positive and negative reaction to PPD skin test. Oncological outcomes, immunological markers (TNF-α and IL-6) changes and BCG side effects were evaluated. RESULTS: There were no significant differences between patients who received PPD or not regarding the 2-year recurrence free survival (RFS) rates and progression-free survival (PFS) rates and immunological markers changes. The 2-year RFS and PFS rates were significantly higher in patients with positive reactions. Post-induction values of immunological markers increased in all patients with a significant increase in patients with positive reactions. BCG side effects were significantly higher in patients with positive reactions. CONCLUSIONS: The intradermal injection of PPD before intravesical BCG has no impact on oncological outcomes of patients with NMIBC treated with TURBT and intravesical BCG. However, the PPD skin test reactions before BCG therapy can predict the oncological outcomes, BCG side effects and the immunological outcomes of patients.

RESUMO

Over the past few years, robotic-assisted laparoscopic ureteral reimplantation (RALUR) has gained popularity as an acceptable alternative for the traditional open approach if surgery is elected for children with vesicoureteral reflux (VUR). We present our technique including the tips and tricks for both male and female patients, including a stepwise approach for ureteral identification in female patients depending on the level of technical difficulty. Our series include 30 patients who represent a spectrum in which we presented the different tips and tricks included in this video.

RESUMO

INTRODUCTION: Double-diaper technique with an open-drainage catheter is a common practice after hypospadias repair. However, double-diapering may increase the burden of postoperative care and has not been compared to single-diapering with an open-drainage catheter. OBJECTIVES: This study investigates whether the single-diaper technique is associated with inferior surgical outcomes compared to the double-diaper technique. MATERIALS AND METHODS: A single surgeon database was retrospectively reviewed for patients who underwent hypospadias repair between 2013 and 2021. Patients who were lost to follow-up and those in whom the type of diaper care (single- or double-diaper) was not documented were excluded. Patients in the single-diaper technique received the same type of dressing and discharge instructions, as those in the double-diaper group, except for leaving the catheter freely draining into a single-diaper. Short-term complications including surgical site infection (SSI), urinary tract infection (UTI) and wound dehiscence, were the primary outcome; whereas the long-term urethroplasty complications (urethrocutaneous fistula and meatal stenosis) were secondary outcomes. Outcomes were analyzed according to the type of diaper care. RESULTS: Among 323 patients reviewed, 219 patients met the inclusion criteria (72 patients in the double-diaper and 147 in the single-diaper group). Both study groups were similar regarding patient demographics, hypospadias characteristics and surgical technique. Looking at the primary outcomes, there was no statistically significant difference in SSI, UTI or wound dehiscence. For the secondary outcomes, the incidence of meatal stenosis (8.3 vs. 1.4%, p = 0.044), and fistula formation (15.3% vs 5.4%, p = 0.037) was significantly higher in the double-diaper than the single-diaper group, respectively (Table 2). CONCLUSION: Single-diaper technique following hypospadias repair is not associated with increased risk of complications compared to double-diaper technique.

RESUMO

INTRODUCTION: Unintentional injury is a leading cause of mortality and morbidity in children. There is no consensus on the ideal, discrete management of pediatric renal trauma (PRT). Therefore, management protocols tend to be institution-specific. OBJECTIVE: This study aimed to characterize PRT at a rural level-1 trauma center and subsequently develop a standardized protocol. STUDY DESIGN: A retrospective review of a prospectively maintained database of PRT at a rural level 1 trauma center between 2009 and 2019 was conducted. Injuries were characterized regarding renal trauma grade, associated multi-organ involvement and the need for intervention. The benefit of patient transfer from regional hospitals and length and cost of stay were evaluated. RESULTS: Of 250 patients admitted with renal trauma diagnosis 50 patients <18 years were analyzed. Of those, the majority (32/50, 64%) had low-grade (grade I-III) injuries. Conservative management was successful in all low-grade injuries. Of 18 high-grade PRT, 10 (55.6%) required intervention, one prior to transfer. Among patients with low-grade trauma, 23/32 (72%) were transferred from an outside facility. A total of 13 (26%) patients with isolated low-grade renal trauma were transferred from regional hospitals. All isolated, transferred low-grade renal trauma had diagnostic imaging before transfer and none required invasive intervention. Interventional management of renal injury was associated with a longer median LOS [7 (IQR = 4-16.5) vs 4 (IQR = 2-6) days for conservative management, p = 0.019)] and an increased median total cost of $57,986 vs. $18,042 for conservative management (p = 0.002). DISCUSSION: The majority of PRT, particularly low-grade, can be managed conservatively. A significant proportion of children with low-grade trauma are unnecessarily transferred to higher level centers. Review of pediatric renal trauma at our institution over a decade has allowed us to develop an institutional protocol which we believe allows for safe and effective patient monitoring. CONCLUSION: Isolated, low-grade PRT can be managed conservatively at regional hospitals without needing transfer to a level 1 trauma center. Children with high-grade injuries should be closely monitored and are more likely to need invasive intervention. Development of a PRT protocol will help to safely triage this population and identify those who may benefit from transfer to a tertiary care center.
